Resumo: | Results of stomach contents analysis of 855 red grouper specimens (Epinephelus morio) caught in Campeche Bank are presented. Individual length composition ranged from 25 to 89 cm fork length (Lf). Fishes (28%), crabs (43%), and shrimps (18%) integrated the main feeding groups in the stomach contents, with no preferential prey-feeding pattern observed. Crabs (33%) are the preferred prey for fish smaller than 55 cm Lf. From this size on fishes (42%) become the most represented items. A significant difference was found in the frequency distributions of preys by regions, with the central region showing the highest abundance. No significant differences in the prey frequency distributions by depth were observed. Feeding activity occurs all around the year, with fish between 32 and 52 cm (Lf) showing the greatest activity.
